The Inno Long bolts for fairings is an optional bolt set for Inno brand fairings. The 6 Long Bolts allows the fairings to be mounted on oversize factory racks, Rhino-Rack crossbars, and Thule Xsporter and Professional truck racks. These replacement bolts allow the mounting clamps to fit around bars between 1" and 2" tall. If you have an Inno or Thule roof rack with square load bars, you do not need these long bolts.
